The week ahead

SAN ANTONIO — The Spurs continue to cruise, extending their win streak to seven games with another perfect week. They’ve got a shot to push the surge to double-digits with a light week, both in volume and quality.

A one-game trip to face the Grizzlies could be tough, but the Spurs have won four of their last six visits to Memphis, with one of the losses coming in overtime. That contest is sandwiched by home dates with Boston and Cleveland, both of whom are struggling to keep up in the dreadful Eastern Conference.

Boston (4-7), 7:30 p.m. Wednesday

Perhaps no team illustrates how quickly things can change in professional sports more than the Celtics. Future Hall of Famers Kevin Garnett and Paul Pierce and head coach Doc Rivers are all gone. The long big-name holdover from their recent golden era is point guard Rajon Rondo, and he’s still out recovering from a torn ACL. The Celtics are limping along without them, dropping three straight after evening their record with four consecutive victories in a row. Such inconsistency is likely to continue as they attempt to rebuild their roster almost from scratch.

at Memphis (5-5), 7 p.m. Friday

Something’s off in Memphis, where the Grizzlies have stumbled out of the gates in their first season under rookie head coach Dave Joerger. They’re struggling to score, which is nothing new. But more concerning is their drop to 19th in defensive efficiency, the cornerstone of their identity. The Grizzlies have gotten some solid performances from Zach Randolph and Marc Gasol in recent outings, and Mike Conley is averaging a career-high 19 points per game. But it will take more than that to erase doubts that firing Lionel Hollins wasn’t the correct play.

Cleveland (4-7), 7:30 p.m. Saturday

Speaking of curious coaching decisions, Mike Brown isn’t making much of an impression in his second go-round with the Cavaliers. They’re on pace to miss the playoffs for the fourth straight year with the NBA’s 29th-ranked offense. Top overall pick Anthony Bennett has been a massive disappointment, scoring just 13 points in nine games while shooting 14.3 percent. Every bit as troubling is the regression of young guards Kyrie Irving and Dion Waiters, whose shooting numbers are both down across the board.
